Abstract

PURPOSE:To simplify a structure which reciprocates a magnetic head while fixing a magnetic sheet, by providing the whole of an internal case, containing a driving mechanism part, rotatably on an external case, and by displacing the internal case so that it is clamped with and released from the magnetic sheet. CONSTITUTION:An internal case 4 is rotated away from an external case 2, and a magnetic sheet 5 is inserted into a gap between a magnetic head 21 and the external case 2 and mounted on a frame 6. A lever 44 is operated to rotate the internal case 4, and the lower end of the sheet 5 is clamped by a guide shaft 24. When a motor 13 is started, a head carriage 7 starts moving along a spiral shaft 17 to perform the reproduction of the sheet 5 by the head 21. Then, when reciprocation is repeated and the reproduction of the sheet 5 is all completed, feeding to the motor 13 is stopped and at the position, i.e., the start position of the magnetic head, the movement of the head carriage 7 is stopped.
